raw materials in coal processing

Waste from the coal extraction process as raw material for ...

In this work the feasibility of utilization of waste originating during the coal extraction process as raw material for the construction industry is studied. During the process, the gross coal extracted from the mine is sent to a purification station and put on a vibrating sieve where particles bigger than 150 mm are separated to be milled.
